From 12 months onward, your little one becomes a lot more active. Our 9-ounce sippy cup is ideal at this stage, designed to keep busy toddlers happy and hydrated all day! The insulated core keeps drinks cool, and the soft flip straw makes it easy to drink on the go. In between sips, the straw flips down to stay clean and stop spills. As with most Tommee Tippee cups, you can interchange parts like lids and bases, although handles are not compatible with insulated cups. The toddler sippy cup is super easy to clean—either in hot, soapy water or on the top shelf of the dishwasher. Helping you Parent On
